    Ive got a 1976 LT Rally Sport with the stock 14"s on it & really want to put a set of 15x8's on the front & 15x10"s on the rear. Question is will this combo work, & if not what size can? Looking at 5 on 4.75 with anywhere from 4" to 4.5" backspacing. I don't want them outside of the fenders. I don't know what size tires to go with either. Just going to run bare rims with the police centers only. Will my combo work?

    15 x 8 on the front is fine.To fit 15 x 10 you would have to mini tub it. I have head of people using 15 x 9 `s in back without much effort. Compared to 16`s-18`s .15`s sidewall bulge out more. your choice.

    You better go 4.5 back space if you can get them. 3.5 back space will rub hard on a 15x8 wheel.

    On my '76 I did 15x8 with 4.5 backspace all around. Tires are 255/60. On large bumps I think I hear an occasional rub, but I know that the suspension is worn out.

    I ended up buying a set of reproduction 15x8 corvette rally wheels with a 4.25" backspacing & 5 on 4.75 bolt pattern. Now I need to find a nice set of tires that look good but don't rub. Hoping to go as wide as possible. What size look good on there?

    Let us know if they fit without rubbing. I have been lusting after Vette wheels for a long time. I think they look good on these cars. I always like 255/60r15's on mine. I cut the fenders years ago to make them work. If the Vette wheels don't rub with 255's I may buy some new fenders. I have to have white letter tires on my hot rods. Blackwalls look cheap and wimpy to me. I can't overdrive 15's and still keep my license on the street anyway.

    A little hammer work on the rear inner wheel well to round the edge. That way if you do get a bit of rub it does not cut. I had air shocks that kept it up so It was rarely an issue unless They ran low or I hit some major pot holes or humps in the road.

    15x8's on the way. Looks like the "safe" size to go on tires would be 225/60/15's all around. I wouldn't mind trying a pair of 255/60/15's on the rears to make it looks better. But from what I understand, Id have to "roll" the rear quarter inner lip to gain clearance. Anybody have a pic of either 225/60/15 or 255/60/15's on the car I could see?

    Those are 255/60 all around on 15x8 with 4.5 backspace.

    What kinda space do you have on the rears towards the inner wells? These reproduction 15x8 rally wheels have a 4.25" backspacing to them. I got them today, I want to get them on the car tomorrow to see if & what I have room for. Thanks for the pic, they look good on there!
